STONE AND OR CRUSHER.

SPECIFICATION forming part 0f Letters Patent No. 519,566, dated May 8, 1894.

Application filed July 28,1893. Serial No. 4811721. (No model.)

To a/ZZ whom it may concern:

Be it known that I, CALEB GROZIER COL- LINs, of Woodsburg, in the countyof Queens and State of New York, have invented a new and Improved Stone and Ore Crusher, of which.

the followingis a full, clear, and exact description.

The invention relates to Crushers for reducing stones, ores and other hard and refractory substances to a pulverized state, and in which a revoluble roll and ring are employed for the purpose.

The Object of the invention is to provide a new and improved Crusher, which is simple and durable in construction, very effective in operation, and arranged to greatly reduce the friction and consequent loss of power and to increase the capacity of the machine. c

The invention consists of certain parts and details and combinations of the same, as will be hereinafter described and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures:

Figure 1 is a side elevation of the improvement with parts broken out. Fig. 2 is a transverse section of the same\on the line 2-42 of Fig. 1. Fig. 3 is a sectional side elevation of one of the bearings for the shaft. Fig. 4 is a sectional plan View of the improvement on the line 4--4 of Fig. 1. Fig. 5 is a side elevation of part of the casing. Fig. 6 is a transverse section of the feed mechanism; and Fig. 7 is a reduced rear elevation of the machine showing more particularly the driving mechanism.

The improved Crusher is provided with a suitable casing A, preferably made in two 1ongitudinal parts fastened together by transverse bolts, as plainly illustrated in the drawings. Within the casing A are arranged two ringsB and B in peripheral contact with each other, and within the rings are arranged crushing rolls C and C respectively, in frictional contact with the interior of the rings directly opposite the contact point of the rings B and B. The ring B is supported on guide rolls D,

D and D2 journaled in suitable bearings in the sides of the casing A and similar rolls D2, D4, D5 support the other ring B within the casing A. Each of the guide rolls D, D', D2, D3, D4 and D5, is preferably formed at its ends with annular flanges extending over the sides of the rings so as to hold the same in proper position. f A

The crushing rolls C and C are secured on transversely-extending shafts E and E rep spectively, of which the shaft E is journaled outside of the casing A in suitable bearings formed on the rocker arms Gand G extending downwardly and secured ony the ends of a rock shaft G2 journaled in suitable bearings in the lower part of the casing A. The other crushing roll C has its shaft E journaled in bearings arranged on therock arms G3 and G4 both attached at their lower ends on a rock shaft G5 also j Ournaled in the sides of the casingA. Through the rocker arms G and G3 passes loosely a rod H secured at its middle between the two rocker arms in a bracket I attached or formed on the front side of the cas- -rods lH and H', the tension of the several springs may be increased or diminished, so as to force the said crushing rolls C and C with more or less force, in Ycontact with the interior surface of the rings B and B respectively. By this arrangement, the rings B and B are likewise forced with more or less force in contact with each other, as the crushing rolls are located on opposite sides of the conltact point of the rings B, B and lare `forced toward each other by the action of their respective sets of springs J, J2 and J', J3. The shafts E and E pass loosely through segmental slots in covers fitted over Openings in the sides of the casing A, the said covers when removed permitting a removal of the crushing rolls C and C in case ofdamage or for other purposes.

On the sides of the casing Aare arranged the feed hoppers K and K' discharging on IOO the crushing roll C, and then `over `a second` pulley C attached to the shaft E of the crushing roll C and then the belt passes over a third pulley O3 secured on the shaft D(i of 4thegnide roller D2, as `plainly indicated in Figs. l and 7. It will be `seen Vthat by this arrangement the beltrevolves the crushing rolls C and C and at the same time, exerts a `pressure onthe said pulleys in such a man.` 4ner `as tot'orce the crushing 'rolls C and C' toward each other, thusaiding `the springsJ, J2 and J', J3. As illustrated in Fig. 3, eachof the several shafts for the guide rollers em-` ployed, has `its `bearing in `a sleeve P fitted into a corresponding` boss A projectingfrom the respective side of the casing A.

The inner end of each sleeve P terminates in 1a cup Qt'astened to the inner `surface of the respective side ofthe casing A and each cup is provided in its bottom with a channel Q extending downwardly and outwardly to register with an aperture A2 likewise inclined and formed in the corresponding side ofthe casing A. Thus, any oil that works `along the sleeve P and shaft accumulates in the cup Q and drains from the latter to the outside of the casing by the channel Q" and opening A2. Thus, no lubricant flows to `the inside of the casing, and into theworking `parts and the material treated by the same. The inside of the casing ispreferably lined with wearing strips R, R', bolted or otherwise secured to the `sides of the frame and adaptedto engage `the side `edges ot' `the rings B and B and crushing rolls C and C.4

When the machine is in operation, the ma-` terial is fed through the hoppers K and K to the crushing rolls C and C `at the `top thereof, `the material then being carried by the corresponding roller between it and its ring to be crushed bythe ring and itsroller coming in frictional contact with each other.

The crushed material passes from the sides of the rings into `the lower open part of the casing to be discharged atfthe bottom there of. It will be seen that bythis arrangement` the rings B and B are forced in .frictional contact with each other by their crushing rolls C and C respectively, and the three points of frictional contact are in alignment i with each other as ,plainly shown in Fig. l and described above.

`Having `thus described my invention, I

`claim as new `anddesireto secure by Letters shown Aand described.

2. Astone and ore crusher comprising revoluble rings in peripheral contact with each other, crushing rolls ininterior frictional contact with the said rings, and at points '1n alignment with the peripheral contact point of the said rings, rocker arms carryingthe shafts for the said crushing rolls andsprings pressing on the said rocker arms -to regulate the frictional contact between the rollsand rings,substantially as shown and descrlbed.

3. A stone `and orecrusher, comprising two ri'gs in peripheral contact with each other, guide rolls for supporting the said rings, crushing rolls in interior peripheral contact with the said rings, rocker arms carrying the shafts of the said crnsher rol-ls, and springs `press- `ing on the 'free ends of the sa1d rocker arms tomove the said ycrushing rolls toward .each other to regulate the Africtional contact with the rings, substantially as shown and de scribed.
